l rares-1T oFFice ERNEST L. SI'ITH, OFSAN FRAN CSCO, CALIFORNIA, ASSIGNOR TO RINGLETTEVPERMA- NENT GOMPANY,.OF SAN FRANCISCO, CALIFGRNIA, A `G0R13ORATION 0F CALIFORNIA HAIR CURLING APPARATUS Application led'March 5, 1929. Serial '.No. 344,256.

This invention relates to lelectrical hair curling or waving apparatus, and particularly to that type ot apparatus set forth in my co-pending application Serial LNumber rlhe principal-objects ot the present invention are to improve the construction of the curling spindle, whereby the same is precluded from twisting from the hair clamping means; to provide an improved heating element terminal connection whereby short circuits and shocks are eliminated. Other objects are to improve the construction of the hair gripping means in the hair clamping device, and to improve the structure ot the hair clamping device.

Additional advantages and objects will appear as the specication proceeds.

lith the above mentioned and other objects in view, the invention consists in the novel construction andcombination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto' appended; it being understood that various changes in the lform, proportion, size and minor details of construction within the scope oic the claims may be resorted to without departing from the spirit or sacrii'icing any of the advantages of the invention.

Referring to the drawings, disclosing the invention- Fig. 1 is a view in top plan of one of the hair clamping devices in closed position.

Fig. 2 is a view in 4top plan with the coniplenientary clamping bars in open position.

Fig. 3 is a view in end elevation of a curling spindle.

Fig. 4 is a view in side elevation of one of the curling spindles, illustrating the hair end clamp in raised position.

Fig. 5 is a view similar to Fig.4, illustrating the hair end clamp in plan,

Fig. 6 is a vertical sectional view through one of the curling spindles, with hair wound thereon, and in position in cooperative relation with one of the hair clamping bars; the covering pad being illustrated as embracing the hair.

Fig. 7 is a view in end elevation on line 7 7 of Fig. 1.

circumferential holding ratchets 2. The

spindle is formed longitudinally with a bore -3,'terminating 'at eac-li end inail-enlarged recess il, in each of which is positioned a disc of insulating material r5., having central aperture 6. rllie outer 'disc faces are `set inwardi ly from the respective ends of the spindle.

- VVithin the `bore 3, between the discs the Aspindle is provided with .a rtubular porcelain insulator' 7.,-'longitudinally Vof which extends lthe coiled heating element '8, the terminal' ends `9 of which project a short distance Ithrough the :apertures 6 in the discs 5.

The surface ot the spindle 1, between hold- :nig ratchets 2, uniformly decreases 1n its cross-'sectional area from its fen-ds toward its center, clearly i-llustratedin Figs. 4 and 5.

This enables a considerable length oit hair "to be wound thereon, and at the same time Amaintains the surface of the hair in aunitorin line from end to end of the spindle. On they surface of the spindle is pivotally mounted the hair end clamp 10, of longitudinal and transverse configuration, ycorresponding to the surfaceof the curling spindle between Ythe ratchets, this being clearly illustrated in4k Figs. 11 and 5.

A hair clamp, consisting of the complementary hair clamping bars 11 and 1:2 hingedly connected at one end by the 'toggle 13, and provided on :opposing .longitudinal edges with ,groove-s' 14, that in the member 11 being oi' slightly greater width than that in inember 12, is provided `to mount a curling .spindle in a hereinafter 'described manner.

Longitudinally ot its .upper surface, the Vclamp is forni-ed with a vdepression 15, arcuate in vcross section. rI "he depression is formed halt within the uppersurface of each complementary clamping bar, and at its ends, the portion of 4the depression i-n one bar is re-lcessed to receive the base 16 of a spring arm 17, terminating at its end'with a ratchet engaging pawl 18, the pawls of the respective spring members overlying the inner edge of their mounting clamping bar. The free ends of the clamping bars are inwardly slotted and one of them carries a bar locking lever 19 for swinging movement into the slot oi' Athe cooperating bar, when the latter are in hair gripping position and the venlarged end 2O of the lever extends to the rear of the bar 12, and thus holds the bars in closed or hairclamping position.

Positioned Within the groove 14 of the lesser width, that in bar 11, is a portion of a tubular elastic hair gripping member 2l, the free edge oi which is adapted to project, when the bars are in closed position, into the groove lect greater width, the present embodiment showing` it in bar l2.

lVith the parts constructed as in the drawings, and as above described, the operator raises from the scalp a lock or portion of hair and while the same is held relatively taut, the bars 11 and 12 are closed on that portion of the lock of hair close to the scalp,

.as in Fig. 6; the elastic member 21 forcing the hair into the groove 14 of greater width, and thus retaining the same therein the lever 19 having been moved to locked position. The operator with the hair end clamp of the spindle 1 raised, winds the extreme end portion of the hair lock around the spindle beneath the clamp 10, lowers the clamp and continues the winding operation, with the hair equally distributed longitudinally of the spindle. Such Winding will naturally bring the spindle close to the clamping device, and the operator gradually passes the ratchets 2 in the spring arms 17 with the pawl 18 in position to engage the ratchets 2. l/Vhen in this position, the operator, by any suitable means or tool, imparts a furtherwinding movement to the spindle, drawing the hair lock tightly thereon. lVhen in such position, the operator positions over the spindle a shield or pad, tightly embracing the same, and which, in the present instance, consists of three layers 'of material, that closest to the lock being felt 22, the next being oil paper 23, and the outside being lexible'material, such as tinoil 24. With the wrapped hair ock thus covered, electrical contacts are made with the terminals 9, causing a heating of the heating element 8, and thus accomplishing the curling or waving operation desired in this particular lock of hair.

If it is desirable, suitable elements 25, such as' cork feet or 'elevating elements may be mounted on the lower surfaceof the bars 11` and 12 to space the Asame from the scalp and insure an air circulation between the scalp and the clamping bars.

I claim 1. In a hair curling and waving device, a

and expansion therein, upon folding of the bars to parallel relation.

2. In a hair curling and waving device, a hair clamp consisting of complementary bars connected by toggle hinge at one end to fold with adjacent side edges in opposing parallel relation, said longitudinal side edges being longitudinally grooved, one groove being of greater width than the other, a tubular elastic hair engaging member tightly held within the groove of lesser width with its free edge adapted for projection into the Wider groove and expansion therein, upon folding of the bars to parallel relation, and means to lock the bars in said parallel relation. Y

In testimony whereof I have signed my name to this specification.
